The embodiment of the invention provides a vehicle body air pressure release valve control system, method and device. The system comprises an air pressure release valve and a control module, wherein the air pressure release valve is provided with a conventional ventilation row plate and a standby ventilation row plate; the opening and closing states of the standby ventilation row plate are controlled through the control module. The control module is used for acquiring a pressure difference value inside and outside the automobile if the automobile is judged to be in a standing automobile door closing working condition; if the pressure difference value between the interior and the exterior of the automobile is larger than a set threshold value, a standby ventilation exhaust plate of the airpressure release valve is controlled to be opened; if it is judged that the automobile is in the driving working condition, a standby ventilation exhaust plate of the air pressure release valve is controlled to be closed. According to the air pressure release valve, the opening area of the air pressure release valve can be adjusted in a self-adaptive mode according to different use working conditions of an automobile, and the problems that when the automobile is closed in a standing mode, the ear pressing feeling occurs, the door closing sound quality becomes poor, the door closing resistancebecomes large, and when the automobile runs at a high speed, noise in the automobile becomes large are solved.
本发明实施例提供一种车身空气泄压阀控制系统、方法及装置,该系统包括:包括:具有常规通风排板和备用通风排板的空气泄压阀和控制模块;其中所述备用通风排板通过控制模块控制其开闭状态;所述控制模块,用于若判定汽车处于静置关车门工况,则获取所述汽车车内外的压力差值;若所述汽车车内外的压力差值大于设定阈值,则控制所述空气泄压阀的备用通风排板开启;若判定汽车处于行驶工况,则控制所述空气泄压阀的备用通风排板关闭。本发明能够针对汽车在不同的使用工况下自适应地调节空气泄压阀的开口面积,避免在汽车静置关门时出现“压耳感”、关门声品质变差、关门阻力变大,以及在在汽车高速行驶时,车内噪声变大的问题。
